Bethesda Softworks announced that Obsidian Entertainment is developing a brand-new Fallout game titled Fallout: New Vegas, to release next year on PC, Xbox 360, and PlayStation 3.

Gamasutra was at Bethesda's event in London to hear the game announced by marketing and PR VP Pete Hines, who provided few specifics on the game's engine, gameplay or perspective -- but did note the game is neither a Fallout 3 sequel nor a spin-off.

"It's not Fallout Tactics -- it's not Brotherhood Of Steel. It's another Fallout game," said Hines. "It has no impact on what [Bethesda Game Studios game director] Todd Howard and his guys are planning."

A number of Obsidian staff are veterans of Black Isle's original Fallout games. The company's CEO, Feargus Urquhart, was instrumental in founding Black Isle, and served as its director.

Hines said Bethesda approached Obsidian to work on the title. "We've really been enjoying working with [Obsidian] on it," he said, adding, "That is all we're going to say about it right now."
